Linux - XBMCbuntu Frodo install, missing initrd

Hi folks! I'm new to xbmc, and decided to jump onboard with the new release. Unfortunately, when I went to boot the Frodo Beta, I was met with a missing file notification: casper/initrd.lz. I looked at each of the disk images available for download, and none of them included this file.

idk what Ubuntu version XBMCbuntu is based on, However a little bird tells me you'll need Quantal or newer kernel for trinity. (if you want the video driver to work.) Alternatively you will need to install Ubuntu minimal + XBMC or use something else like Openelec.
